Differential reduction drives on opposite sides of a vehicle are steer driven by a pair of worm gears (110) meshed with worm wheels (111) inputting steering torque into each reduction drive. The worm gears are rotationally interconnected so that the steering torque applied to the reduction drives is respectively equal and opposite. The arrangement allows a simple steering control shaft (46) to receive steering control torque for normal turning and driving torque for propulsion drive-assisted pivot turning. A pivot turn brake (120), applied to the drive t...
A steer-driven reduction drive system comprising: a. a pair of differential reduction drives arranged respectively on opposite sides of a vehicle, each of said reduction drives having a worm wheel input used exclusively for input of steering control torque to said reduction drives; b. a pair of worm gears meshed respectively with each of said worm wheel inputs to said reduction drives; c. a steering control shaft spanning the distance between said worm gears; d. bevel gears on end regions of said control shaft being meshed respectively with bevel gears t...
